For the record, the build 0524 is the only stand-alone version. The rest are the UPMEM chip only, thus in order to play them you have to attach it at the end of sk.bin + s2.bin, a simple bcopy will work. I might upload "mounted" versions later.

Awkward behavior (Knuckles getting hurt a lot and jumping in weird places) in the demos that appear if you don't press anything on the title screen, compared to the final. (presumably because they left Sonic's demos intact from Sonic 2)

Project:Part of Team Megamix, but haven't done any actual work in ages.

In final S2K, they added a check in knuckles' jump routine for demo mode, and if such they set the jump height to sonic's jump height, which fixes around half the demos. However, they didn't re-insert the mid-air speed cap in demo mode, so the EHZ and ARZ demos still screw up.

Ah, thank you for clarifying that for me. So as I understand it, the game still reads the demos straight from the S2 data, just with the workaround applied to make Knuckles jump like sonic (but not move as fast as him in the air), and it wasn't created yet as of 0524.

I guess I'll check to see where this was added (if it was in any of these protos) and edit it back in this post later. ^^

EDIT - That was quick.... I guess they added it by 0606. Speaking of 0606, they added the Knuckles logo by that build.
